  • Phase I: Assembly Validation

  • HEPI

  • Overview: Mechanical assembly (no Instruments)

  • No particular tests (rigid connection between cross beams and piers). No report.

  • Final check is the leveling.

  • Assembly validation is responsibility of SEI installation lead (Jeremy @ LLO, Hugh @LHO)

  • HAM-ISI

  • Overview: Sub-assembly check, Inventory, Balancing, Check & adjust gaps, Range of motion, Static tests, Linearity tests, Power spectrums, Transfer functions…

  • Main page: E1000305 - aLIGO HAM-ISI Testing and Commissioning Documentation

  • Procedure: E1000309 - aLIGO HAM-ISI, Pre-integration Testing Procedure, Phase I (post-assembly)

  • Report Example: E1000326- aLIGO HAM-ISI, Pre-integration Test Report, Phase I, LLO Unit #2

  • BSC-ISI

  • Overview:Similar to HAM-ISI. Twice many stages.

  • Main page:E1000306 - aLIGO BSC-ISI Testing and Commissioning Documentation

  • Procedure: E1000486 - aLIGO BSC-ISI Testing Procedure, Phase I (Post-assembly)

  • Report Example:E1100294 - aLIGO BSC-ISI, Pre-integration Test Report, Phase I, LHO Unit #1

  • Phase II: Integration

  • Everything between the end of the module assembly and closing the chamber.

  • In other words, all the testing related to merging with other modules

  • HEPI

  • Overview: Check that HEPI is ready to receive an ISI or Stack (Stops, Leveling…)

  • Check actuators and sensors (L4C power spectrums, IPS DC values…)

  • Install ISI (or passive stack)

  • Unlock HEPI. Monitor dial indicators, load cells.

  • Level HEPI.

  • Connect actuators.

  • Set IPS gaps.

  • Check the control software (SEI and SUS Watch dogs)

  • Test HEPI (Range of motions, Transfer functions, turn on low performance loops)

  • Leveling, alignments.

  • Report and validation of phase II.

  • Phase II: Integration

  • Everything between end of the module assembly and closing the chamber

  • In other words, all tests related to merging with other modules

  • HAM-ISI

  • Phase II starts when the HAM-ISI unit is mounted on a stand in the observatory (LVEA or End Station)

  • Two-case scenario:

  • Assembly already completed and fully tested in the assembly building (i.e. HAM-ISI 8 & 9 @ LHO)

  • Minimum side chamber testing before insertion (DC values of CPS, power spectrums of GS13s…) . Could be done without electronic rack if not available. Testing completed after the chamber is closed.

  • Assembly completed in LVEA or End Station (Install GS13, CPS Shield…)

  • Need Side Chamber Testing before Installation.

  • After installation in the chamber:

  • - Platform is being populated with optics

  • - Testing sequence to be detailed chamber per chamber.

  • Report, Validation

  • Close the chamber: End of Phase II

  • Phase III: Control Commissioning

  • In other words, all tests related to merging with other modules

  • BSC-ISI

  • Phase II starts when the BSC-ISI unit is mounted on stand in the observatory (LVEA or End Station)

  • Check functionalities (Static Tests, Transfer functions). Compare with measurements after assembly (Phase I)

  • Test control functionalities (Damping, Level 1 control…)

  • Integration with optical components. Testing is chamber specific, function of the optics installation sequence.

  • Installation in the chambers

  • Test basic control functionalities in the chamber (Damping, Level 1 control…)

  • Report, Validation

  • Close the chamber: End of Phase II

  • Phase III: Control Commissioning
